Generate printable broad-edge calligraphy guide sheets with pen-angle hatch marks, nib-width ladders and correct x-height for each hand.
The Nib Angle Practice Grid generates printable broad-edge calligraphy guide sheets ruled in nib widths, which is how calligraphic hands are actually measured, and prints hatch marks at the correct pen angle along every baseline. Choose a hand — Foundational at 30° with a four-nib-width x-height, Italic at 45° with five, Blackletter at 40°, Uncial at 20° — plus your nib width and page size, and it works out the x-height, ascender and descender bands, the row pitch and how many line sets fit on the sheet. It also predicts the stroke widths a nib should produce, since a vertical pull at angle A gives a stem of nib width × cos A and a horizontal pull gives a bar of nib width × sin A.

The x-height follows the hand, not an arbitrary millimetre value, so proportions stay correct at any nib size.
Hatch marks at the pen angle give a reference to align the nib against instead of eyeballing it.
Measure a stem against the calculated nib width × cos A figure to confirm your angle is really where you think.
Foundational and Carolingian are written at about 30°, Italic at 40–45°, Blackletter (Textura) at 40–45°, and Uncial at a shallow 20–25°. The angle is measured between the nib edge and the horizontal writing line.
It depends on the hand: Foundational is 4 nib widths, Italic and Blackletter are 5, Uncial about 4, and Roman capitals stand about 7 nib widths from baseline to cap line. Ascenders and descenders typically add another 2–3 nib widths each.
Because a vertical downstroke made at a pen angle only exposes part of the nib edge. The stem measures nib width × cos(angle), so a 3.8 mm nib at 30° draws a 3.29 mm stem, and at 45° a 2.69 mm stem. If your stem is thicker than predicted, your pen angle is shallower than you think.
Yes. Turn off “fit to page” or “shrink to fit” in the print dialog, or every measurement on the sheet shrinks and the nib-width ladder will no longer match your pen. Check by measuring the x-height on the printed sheet against the figure shown on screen.
